Users of the crypto currencies such as BItcoin, Litecoin or Dogecoin will be more than aware of the fluctuations of these alternative currencies and wish to keep an eye on their value compared to the dollar as much as possible. A fun and easy way to do this is to used a networked Raspberry Pi to retrieve pricing data and display it on an LCD.

You can make your own device to do just that with the help of Make: who have described an easy weekend project that you can finish in a few hours. A typical HD44780-compatible LCD is used with a degree of wiring, however a serial OLED could reduce the work even further. The folks from Make: give an animated demonstration of their project in the following video:

Looking for a small yet useful display for your Raspberry Pi (or Arduino)? Then check out our new 128x128 pixel OLED Module. With a diagonal size of 1.5" and 16,384 colours to select from, so almost anything is possible. Furthermore there's a microSD card socket, and removable tabs on each side which can hold LEDs and buttons:

And using the module is made simple - we have tutorials and drivers for both the Arduino and Raspberry Pi platforms - great for experimenters or those who use both systems. Furthermore, check out the forum where members are already creating modified drivers to rapidly increase the display speed. For more information including our Quickstart guides - and of course to order - visit the OLED Module product page.
